Problem with Ebay.

I'm using Win7 and have a number of browsers available. Safari, Chrome, IE11, Firefox and a really neat browser called Flashpeak. Plus Opera12 and Opera18.
When I view an item on Ebay, clicking on the item's image - top left - will normally open an enlarged window containing the image(s). This happens corectly in all browsers except Opera 18 when accessing Ebay.co.uk. It works fine with the US Ebay but not with the English link. Can this be fixed?
